tikz 思维导图看起来很糟糕

Question

根据 Sigur 在评论中的建议，我增加了级别距离，以便节点分离看起来合理，但我得到的图像仍然很奇怪（过渡继续具有不受欢迎的橙色）：

预期结果会更像这样：

Answer 1

过渡颜色“错误”的原因是您没有使用环境mindmap的可选参数tikzpicture。

以下是我通过尝试一个最小示例来尝试了解哪里出了问题，从而找到问题所在。以下示例基于 PGF/TikZ 手册版本 3.0.0 第 6 章中的示例。

没有思维导图可选参数：

\documentclass[margin=2mm]{standalone}

\usepackage{tikz}
\usetikzlibrary{mindmap}

\begin{document}
\begin{tikzpicture}[
    %mindmap,                   %% NOTE: mindmap optional argument commented out!
    every node/.style=concept,
    concept color=black!20,
    grow cyclic,
    level 1/.append style={level distance=4.5cm,sibling angle=90},
    level 2/.append style={level distance=3cm,sibling angle=45}
    ]
  \node [root concept] {Computational Complexity} % root
    child [concept color=red] { node {Computational Problems}
      child { node {Problem Measures} } 
      child { node {Problem Aspects} }
    }
    child [concept color=blue] { node {Computational Models}
      child { node {Turing Machines} }
      child { node {Random-Access Machines} }
    };
\end{tikzpicture}
\end{document}

使用思维导图可选参数：

\documentclass[margin=2mm]{standalone}

\usepackage{tikz}
\usetikzlibrary{mindmap}

\begin{document}
\begin{tikzpicture}[
    mindmap,
    every node/.style=concept,
    concept color=black!20,
    grow cyclic,
    level 1/.append style={level distance=4.5cm,sibling angle=90},
    level 2/.append style={level distance=3cm,sibling angle=45}
    ]
  \node [root concept] {Computational Complexity} % root
    child [concept color=red] { node {Computational Problems}
      child { node {Problem Measures} } 
      child { node {Problem Aspects} }
    }
    child [concept color=blue] { node {Computational Models}
      child { node {Turing Machines} }
      child { node {Random-Access Machines} }
    };
\end{tikzpicture}
\end{document}

固定思维导图：

我需要增加纸张的尺寸，增加水平距离以使圆圈不重叠，并增加文本宽度以改善文本对齐。

\documentclass[article, 12pt, oneside]{memoir}

\usepackage[a2paper]{geometry}
\usepackage{tikz}
\usetikzlibrary{mindmap}
\pagestyle{empty}
\begin{document}
\begin{tikzpicture}[
    mindmap,
    grow cyclic, text width=4cm, align=flush center,
    every node/.style={concept},
    concept color=orange!40,
    level 1/.style={level distance=10cm,sibling angle=90},
    level 2/.style={level distance=6cm,sibling angle=45}]

\node [root concept] {ShareLaTeX Tutorial Videos}
   child [concept color=blue!30] { node {Beginners Series}
        child { node {First Document}}
        child { node {Sections and Paragraphs}}
        child { node {Mathematics}}
        child { node {Images}}
        child { node {bibliography}}
        child { node {Tables and Matrices}}
        child { node {Longer Documents}}
    }
    child [concept color=yellow!30] { node {Thesis Series}
        child { node {Basic Structure}}
        child { node {Page Layout}}
        child { node {Figures, Subfigures and Tables}}
        child { node {Biblatex}}
        child { node {Title Page}}
    }
    child [concept color=teal!40]  { node {Beamer Series}
        child { node {Getting Started}}
        child { node {Text, Pictures and Tables}}
        child { node {Blocks, Code and Hyperlinks}}
        child { node {Overlay Specifications}}
        child { node {Themes and Handouts}}
    }
    child [concept color=purple!50] { node {TikZ Series}
        child { node {Basic Drawing}}
        child { node {Geogebra}}
        child { node {Flow Charts}}
        child { node {Circuit Diagrams}}
        child [concept color=green!40]  { node {Mind Maps}}
    };
\end{tikzpicture}
\end{document}

Answer 2

只需增加适当的键：

\documentclass[article, a4paper, 12pt, oneside]{memoir}

\usepackage{tikz}
\usetikzlibrary{mindmap}
\pagestyle{empty}
\begin{document}
\begin{tikzpicture}[grow cyclic, text width=2cm, align=flush center, every node/.style=concept, concept color=orange!40,
level 1/.style={level distance=7cm,sibling angle=90},
level 2/.style={level distance=4cm,sibling angle=45}]

\node{ShareLaTeX Tutorial Videos}
   child [concept color=blue!30] { node {Beginners Series}
        child { node {First Document}}
        child { node {Sections and Paragraphs}}
        child { node {Mathematics}}
        child { node {Images}}
        child { node {bibliography}}
        child { node {Tables and Matrices}}
        child { node {Longer Documents}}
    }
    child [concept color=yellow!30] { node {Thesis Series}
        child { node {Basic Structure}}
        child { node {Page Layout}}
        child { node {Figures, Subfigures and Tables}}
        child { node {Biblatex}}
        child { node {Title Page}}
    }
    child [concept color=teal!40]  { node {Beamer Series}
        child { node {Getting Started}}
        child { node {Text, Pictures and Tables}}
        child { node {Blocks, Code and Hyperlinks}}
        child { node {Overlay Specifications}}
        child { node {Themes and Handouts}}
    }
    child [concept color=purple!50] { node {TikZ Series}
        child { node {Basic Drawing}}
        child { node {Geogebra}}
        child { node {Flow Charts}}
        child { node {Circuit Diagrams}}
        child [concept color=green!40]  { node {Mind Maps}}
    };

\end{tikzpicture}
\end{document}
